Pa` 5 June 18, 1985 Daniels Pit 2 C. Farrell D. Colorado Division of Highways - This operation predates the presence of Academy Boulevard. Many years ago Academy ended at Drennan Road. Then the highway was extended southward to connect with Interstate 25 and in the process split the operation into a west and east section. In the process of building the highway they had to cut deeply into the terrace structure forming the sand deposit. This produced the very high and steep walls on Academy at this location. Maintenance problems on the highway have been difficult as a result of the high and steep slopes. One of the purposes of the amendment is to provide a means to reduce these slopes so as to create a more easily maintained roadway. Therefore, the effects of this amendment on that structure will be to improve the rather difficult situation of erosion off of the roadsides and onto the highway. A berm of approximately 12 feet will be left along the highway and therefore functionally the operation will have no more effect than it currently does. But by lowering the road cuts to 12 feet it will improve the highway situation and if anything reduce the adverse effects on the road. In conclusion, there are no adverse impacts on the roadway. The plans included in this amendment, at the very least, will have no change on the highway integrity and in all probability will improve the integrity of the roadway by reducing maintenance problems that are a real headache to the Highway Department as well as unnecessarily expensive to the taxpayers. E. Power Line - The powerline which extends along the east side of Academy Boulevard is a major line. The footings for the support poles extend as far into the ground as the poles are above ground. The only way the stability of Chese poles can be affected would be by excavating well below the level of the poles immediately adjacent to them. All excavations along the powerline will start at the level of the base of ~-- ~ the poles and at least twenty five feet east of the poles. It will then \ extend downward along a 3:1 slope. Therefore, the base of a 60 foot slope would be about 200' from the vertical line delineating the power pole and its underground support. Furthermore, these poles, as shown on the maps, are double poles. If they were single poles then we would have to stay much further from the base with our extraction, but the fact that they are double poles provides much greater stability and security. 1 It is also important to point out that the condition to be created by mining to the east of the powerline is somewhat similar to the situation below and west of the powerline. A steep slope decends from the powerline down to Academy Boulevard. This slope is much steeper than the one that will be produced by Daniel's Sand. No problems have occurred with respect to stability on the highway side and because the slope produced by Daniel's Sand will be even less steep, the possible adverse effects on the powerline stability will be even less than those produced by Academy Boulevard.
